About this mod

YAMEO is a lightweight UE5 Engine.ini mod tailored for midrange hardware. It optimizes rendering, reduces pop-in, and boosts CPU/GPU multithreading by tweaking film grain, anti-aliasing, Lumen, DLSS, texture streaming, shader compilation, and async load settings.

Permissions and credits
YAMEO is optimized for Nvidia GPU and G-Sync monitor.

What is YAMEO?
  • Core Rendering Tweaks
    • Disables film grain, chromatic aberration, and color fringe for a cleaner image.
    • Sharpens tonemapper output (r.Tonemapper.Sharpen=0.5) for crisper visuals.
  • Anti-Aliasing & Upsampling
    • Enables Temporal AA (TAA) with balanced sharpness and upsampling.
    • Integrates NVIDIA DLSS in Balanced mode for improved framerate without sacrificing quality.
  • Global Async & Multithreading
    • Activates async compute, shader precompilation, and multithreaded shader compiling.
    • Offloads rendering tasks to RHI, graphics, and render threads to maximize CPU usage.
  • Texture & Streaming
    • Allocates 90 % of VRAM to texture pool for 8 GB GPUs.
    • Fully loads used textures at startup to eliminate runtime pop-in.
  • Shader & Garbage Collection
    • Boosts shader pipeline cache performance.
    • Enables parallel GC and multithreaded destruction to reduce hitches.
  • User Controls
    • VSync off, Allow Tearing enabled for uncapped framerates.
    • Mouse smoothing and view acceleration disabled for responsive input.

TROUBLESHOOTING

1. No G-Sync Monitor.
Paste under /Script/Engine.RendererSettings

  • r.VSync=1
  • r.D3D12.UseAllowTearing=0
  • t.MaxFPS=142
2. Disable Lumen for Maximum FPS
To reclaim GPU cycles, fully disable dynamic GI and reflections.
Paste under /Script/Engine.RendererSettings

  • r.Lumen.GlobalIllumination=0
  • r.Lumen.Reflections=0
  • r.Lumen.SceneDetail=0
  • r.Lumen.SceneLightingQuality=0
3. Low-VRAM GPUs (≤4 GB)
Reduce texture pool and stream on demand to avoid out-of-memory hitches.
Place under [TextureStreaming]

  • PoolSizeVRAMPercentage=65
  • r.Streaming.FullyLoadUsedTextures=0
4. Weak CPUs (<6 Cores)
Lower async loading and shader-compile threads to prevent CPU contention.
Paste under /Script/Engine.StreamingSettings and [ShaderCompiler]

  • s.AsyncLoadingThreadEnabled=1
  • s.AsyncLoadingThreadPriority=1
  • bAllowAsynchronousShaderCompiling=1
  • MaxShaderJobs=300
5. No Anti-Aliasing (Ultra-High FPS)
Turn off all anti-aliasing for max throughput on very low-end GPUs.
Under /Script/Engine.RendererSettings

  • r.DefaultFeature.AntiAliasing=0
  • r.PostProcessAAQuality=0
6. Balanced NVIDIA DLSS (RTX Cards)
Enable DLSS Balanced mode for ~30 % FPS uplift with good image quality.
Paste under /Script/Engine.RendererSettings

  • r.NGX.DLSS.Enable=1
  • r.NGX.DLSS.Quality=1
  • r.NGX.DLSS.AutoExposure=1
  • r.NGX.DLSS.EnableAutoExposure=1
7. AMD XeSS Users
If you’ve installed the AMD FidelityFX Super Resolution plugin, swap in these lines under /Script/Engine.RendererSettings

  • r.XeSS.Enable=1
  • r.XeSS.Quality=1
8. Disable Nanite & Lower Shadows
Turn off Nanite and drop Virtual Shadow Map resolution for smoother performance in geometry-heavy scenes.
Under /Script/Engine.RendererSettings

  • r.Nanite=0
  • r.Shadow.Virtual.MaxResolution=512
9. Cheapest Reflections M
ethodFallback to simple screen-space reflections instead of expensive ray-trace or Lumen.
Paste under /Script/Engine.RendererSettings

  • r.Reflections.Method=0
Usage:
  • Identify your performance bottleneck (tearing, low FPS, stutters, VRAM/OOM, CPU spikes).
  • Copy the matching snippet above (just the lines).
  • Paste into your Engine.ini under the indicated section, save, set Read Only, and run the game.
